Hi, firstly my apologies, I'm really not that technical. I've been looking to buy a cheap ANT+ USB stick that is compatible with TTS4, the TACX cadence sensor and my Garmin HRM. There appear to be loads of cheap USB sticks out there that suggest that they are compatible with a specific device. Is this really the case? Could I buy a generic ANT+ USB stick that will work with any of my kit? Grateful for your advice.

In principle, you can use any generic ANT stick. Some truly old ones (by now) and afaik the Suunto mini movestick have only 4 channels, so if you keep adding ANT devices (power meter, ...) you may run out of channels. I think nowadays you are pretty much safe to get an 8-channel ANT stick if you buy new (and stay away from the Suunto).

It is advisable, however, to have that ANT stick on an extension to avoid interference (the PC power supply can be a real issue). So you may want to get a 1.5 m USB extension cable, a „USB dock“ extension or something stylish like the Tacx ANT antenna depending on your pain cave style requirements.

An additional question - I upgraded my iGenius to the smart Genius last night. Trying to use the trainer now, it keeps freezing within 15 minutes of riding - it goes into "pause" mode, indicating the signal between the brake/computer ends. Does this have anything to do with the original ANT stick that came with the iGenius - in other words, do I need to buy the new ANT available? Many thanks for input.

There is a very old T1991, which is no longer compatible with the TTS4.

Yes, the T1991 is a USB1.1 ANT device that will not work at all. Probably not many of them floating around anymore. The Tacx T2028 ANT+ antenna actually works pretty well and comes with a cable on a fairly sturdy base. I would strongly recommend the use of some kind of USB cable that places the antenna close to the trainer (total cable length should not be any longer than 5 meters/15 feet).

Don‘t think so. First thing I would check is the power settings of your PC. Sounds like USB ports powered off after 15 min. Odd that it worked before though. Windows updates may reset power settings.

I would look at the number on the ANT transmitter. As I recall, there were others after the T1991 and before the T2028 that did work very well. Also, be sure the transmitter is on a USB extension cable next to the trainer. Many people drape it over the handlebars or place it on a short stool in front of the trainer.
